Can I fuse it face down on
Can I fuse it face down on non irid glass (if it’s a transparent irid)
or lay a sheet of clear or colored transparent glass on top and still get that irrid sparkle while mainting the gloss of the clear/trans glass?
Yes, but be careful of creating bubbles
Is the firing process different;
should I ramp up and anneal/cool slower with irrid in my pieces?
